Way cool! (I seem to be on a mushroom/saprophyte kick here… oh well… ;~)
Seems the cardboard recycling industry is glutted. So what to do instead? Use the cardboard boxes that are forests in a Box, thanks to the brilliance of Paul Stamets, the mushroom guy.
The boxes are impregnated with tree seeds and mushroom spores, and… Add Water… le voila!
Now to dig up all the concrete in downtown Baltimore and start planting these moistened boxes… ;~)
(thanks, Tim, for the info)
